In figure: coiled pipe 1, C-shaped pipes 101, straight tube 102, back-shaped sealing ring 2, square valve body 3, runner 4, arch valve plate 5,
Valve rod 6, heat absorption convex block 7.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, the inner wall of a kind of high temperature resistant bouble-bow shape valve plate side butterfly valve, including square valve body 3, square valve body 3 turns
Dynamic to be connected with valve rod 6, the upper end of valve rod 6 runs through the roof of square valve body 3 and is connected with runner 4, and the lower end of valve rod 6 is through rectangular
The bottom wall of valve body 3, symmetrically arranged arch valve plate 5 is socketed on valve rod 6, and two arch valve plates 5 pass through circumferentially distributed first
It is bolted, two arch valve plates 5 form a confined spaces, cooler are equipped in confined space, between two arch valve plates 5
Equipped with elastic washer, and two opposite sides of arch valve plate 5 are respectively connected with heat absorption convex block 7, improve heat absorption efficiency.
Cooler includes coiled pipe 1, and coiled pipe 1 is composed of C-shaped pipes 101 and straight tube 102, two neighboring straight tube 102
The same end by C-shaped pipes 101, and two neighboring C-shaped pipes 101 are arranged in a crossed manner, and the side of valve rod 6 is run through at the both ends of coiled pipe 1
Wall and the end for extending valve rod 6, facilitate installation.
The edge of two opposite sides of arch valve plate 5 passes through second be circumferentially arranged and has been bolted back-shaped sealing ring 2,
